Step 1: Understanding the Concept:
This question asks for a specific detail from Anton Chekhov's one-act play, "The Proposal". There appears to be a typographical error in the dog's name in the question.
Step 2: Detailed Explanation:
In "The Proposal," the characters Lomov and Natalya argue heatedly about whose dog is better. Lomov's dog is named Guess, and he bought him for 125 rubles. Natalya's dog, belonging to her father Chubukov, is named Squeezer. During their argument, Natalya states the price of her dog: "Papa gave eighty-five roubles for his Squeezer, and Squeezer is heaps better than your Guess!". The name "Leep" in the question is a typo for Squeezer. The price mentioned for Squeezer is 85 rubles.
Step 3: Final Answer:
Assuming "Leep" is a typo for Natalya's dog, Squeezer, the price was 85 rubles. Therefore, option (C) is the correct answer.
